Get rid of outdated alcoholic drink (4)
I believe the answer is:
sack
This clue might be a double definition.
'get rid of' is the first definition.
(as in sacking a worker)
'outdated alcoholic drink' is the second definition.
'sack' can be an answer for 'drink' (sack is a kind of drink). I'm not sure about the 'outdated alcoholic' bit.
Can you help me to learn more?
(Other definitions for sack that I've seen before include "Fire - plunder and destroy" , "It carries coal" , "Loot the large bag" , "See 12" , "boot" .)
